衰老是一个不可避免的条件,折磨着所有的人类。最近的成就,如诱导多能干细胞的产生,提供了初步证据,表明减缓和逆转衰老过程是可能的。然而,这些技术通常涉及完全去分化,即随着细胞转化为多能状态,体细胞身份丧失。将重编程的复壮特性与去分化分离是一个有希望的前景,称为表观遗传复壮。重编程诱导的复壮策略目前涉及使用Yamanaka因子(通常瞬时表达以防止完全去分化),并且是安全地降低生物年龄的有希望的候选者。在这里,我们回顾的发展和潜力的重编程诱导的振兴作为一种抗衰老策略。
Ageing is an inevitable condition that afflicts all humans. Recent achievements, such as the generation of induced pluripotent stem cells, have delivered preliminary evidence that slowing down and reversing the ageing process might be possible. However, these techniques usually involve complete dedifferentiation, i.e. somatic cell identity is lost as cells are converted to a pluripotent state. Separating the rejuvenative properties of reprogramming from dedifferentiation is a promising prospect, termed epigenetic rejuvenation. Reprogramming-induced rejuvenation strategies currently involve using Yamanaka factors (typically transiently expressed to prevent full dedifferentiation) and are promising candidates to safely reduce biological age. Here, we review the development and potential of reprogramming-induced rejuvenation as an anti-ageing strategy.
